AEROPLAN E Application filed November 13, 1929. Serial No. 406,746.

Another object of my invention is the provision of an aeroplane ofsimple and 1nex-.

pensive construction, yet durable and efiicient in its operatlon.

A further ob ect of the invention is the provision of a sul. stantiall vsquare shaped aeroplane equipped with a stabilizing plane or wing, andhorizontal and elevation steering means and with ailerons forcontrolling the rolling motion of the plane and braking its landingforce, as well as a pontoon for floating on water.

These and other objects and advantages of my invention will become morefully known as the description thereof proceeds,

as and will then be specifically defined in the .appended claims.

In the accompanying drawings, forming a material part of thisdisclosure:

Fig. 1 is a top plan view of an aeroplane 3g constructed according to myinvention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a fragmentary sectional top plan view of the planeillustrating the wing operating mechanism on a somewhat enlarged scale,with wings spread. I

Fig. 4 is a front end elevation thereof with the wings closed.

Fig. 5 is a sectional detail top plan view of the rear landing gear, andtriangular pontoon for floating on water.

Fig. 6 is a perspective view of the wings.

As illustrated, the body of the aeroplane in form of a cabin 10, has atits front one starting and landing wheel 11 and at its rear landing andstarting wheels 12 at the ends of an axle 13 journaled in a bearingformed by a. substantially triangularly shaped pontoon 14.

A stabilizing plane or wing 15 has the cus- 60 tomary rudders l6 pivotedto vertical pins 17 provided at the rear end thereof, while an elevationrudder is indicated at 18 and ailerons at 19. i

A pair of triangular wings 20, 21, having a suitably curved body are attheir inner meeting edges secured on rods 22, 23, the straight frontends of which project from the wings while their rear ends are somewhatcurverh'as at 24, and then end in straight extremities 25 journaled insuitable bearings it? on the aeroplanes fuselage.

The straight front ends carry gears 27,28,

and in front of them the ends of shafts orrods 22. 22' are united by amember 29 the front end of which is pivotally secured, as at 3t), to thelip of a sleeve 31, provided with inner thread adapted to engage thethreads of a transverse bar 32 carrying a hand wheel 33.

The gear 27 is also in mesh with a larger gear ill on a shaft 35journaled in a bracket 36. Shaft 35 carries also a bevel gear 37, inmesh with a bevel gear 38 at the end of a shaft :39 carrying at itsopposite end another bevel gear in mesh with a bevel gear 40 on a shaft41 equipped with a hand wheel 42.

The shaft 39 of gear 38 carries also a bevel gear 43 in mesh with abevel gear 44: on they shaft 45,'the motor 46 is provided on a bracket47 attached to the front end of the body 10 and said motor drives apropeller 48 and can be controlled from the cabin.

The operation of my device will be entirely clear from the abovedescription and by simultaneous inspection of the drawings. Theaeroplane is started in the usual manner by the operation of propeller48. The steering is done in the customary well known manner, but theside steeringon either side, for left side left steering, for the rightsidev the right steering (16).

It will be clear that in emergency cases the pontoon will keep the craftafloat and the sails in this case when properly set will allow apropulsion of the craft in case of motor. defects.

It will be understood that I have described and shown the preferred formof my invention only and that Imay make such changes in" itsconstruction as come within the scope of the appended claimswithoutdeparture ,from the spirit of the invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. An aeroplane comprising a body, means for propelling said body,steering means, danding gears, a pair of wings, adapted to 'act assails, means for setting the same, and w a triangularly shaped pontoonto float the craft on water.

2. An aeroplane comprising a body including a cabin, stabilizing meansconnected therewith, steering and landing gears, a pair of wings ofsubstantially triangular shape,

rods to'which said wings are secured at their inner meetiri'g edges, andmeans to operate said rods z'lor'tilting up said wings, and set the samefor acting as sails.

3. An aeroplane comprising a body, a front landing wheel, a pair of rearlanding wheels, a triangular pontoon member carrying said rear landingWheels attached to the body, horizontal and elevation rudders, apropeller,

tilting wings, and means for operating said wings.

4. An aeroplane of the class described comprising a. cabin body, a pairof substantially triangular wings rods to which the inner 39 meetingedges 0 said wings are attached,

arings for said rods, the rear ends of said rods curved and straight, atrain of bevel gearsfor allowing a tilting of said wings, and means onfront end of said wings to move the tilted up sail wings to the left orri ht.

5. In an aeroplane of the clas'sdescrib a pair of wings, means to whichsaid wings are connected to allow a. tilting up of the same, a member towhich said means are pivotally 40 connected, a transverse threaded rodcarrying said member, and provided with a hand wheel, for allowing alateral displacement of the wings, with respect to the body of theaeroplane.

6. In an aeroplane of the class described, a pair of win rods carryingthe inner side edges of sai wings, bearings for said rods, a train ofgears connected with said rods, means 7 for allowing a lateraldisplacement of said rods and wings, and a means for setting said wings.

In witness whereof I have signed my name to this specification.

EMIL JUST.
